Concerns over privacy have haunted GM’s OnStar business for as long as it’s been around, and responses like this video have become something of an annual routine for OnStar’s executives. The latest round of furor involves changes to OnStar’s policies, which the New York Times describes thusly

The first regards what happens when a customer cancels the service. Until now, when OnStar service stopped, so did the vehicle’s two-way communications system. As of Dec. 1, however, that will not necessarily be the case. Vehicles of owners who no longer subscribe could still be monitored via the system’s still-active two-way cellular link.

The second policy change concerns the potential use of the data collected by OnStar, which includes information like the vehicle’s speed and location, current odometer reading, driver seat-belt use and air-bag deployment. Under the new terms, OnStar reserves the right to share that information with other companies and organizations, even data culled from motorists who no longer subscribe to the service but who have left the two-way communications connection open.

Of course, OnStar says GM customers can opt out of the service, but it’s making the case that by only sharing anonymous data, it can limit meaningful privacy concerns. But OnStar doesn’t exist in a vacuum, and as it continues to sell Americans on the notion that security is worth sacrificing some sense of privacy for, it will find itself increasingly pulled into a national debate.

[Ed: The above video is not intended as a specific example of the problems we faced, but a general illustration of the wider issue]

While on a junket for the Hyundai Veloster I was treated to yet another instance of The Most Infuriating Thing About New Cars – the lack of any decent way to connect your iPod to the in-car entertainment system.

As TTAC Editor-In-Chief Ed Niedermeyer and I toured Oregon’s various scenic byways in the newest Hyundai, our musical selections were repeatedly interrupted due various errors, whereby Ed’s iPhone was unable to sync, refused to completely sync, or randomly re-synced. Our attempts at listening to the new Bon Iver album, or Burn After Rolling (the listenable mixtape made by limp-dick rapper Wiz Khalifa) were interrupted by a blast from XM’s pop station, as the iPod integration took a giant shit on us. Nothing spoils the conversation like having your ambient rock or gangsta rap interrupted by Katy Perry or Lady Gaga.

The theme that’s emerged most clearly from my interview with Bob Lutz was, somewhat counterintuitively, compromise. Every vehicle that’s developed and built is the product of nearly countless compromises, on everything from performance to efficiency, and from weight and materials to cost. The question isn’t so much if you compromise when developing a new car, but how you compromise… as was demonstrated in our last Lutzian anecdote. And even during my interview, as the conversation bounced from GM to Chrysler, from mass-market products to niche halo cars, I was thrilled that this issue kept coming up. Why? Because this theme played perfectly into the question that was at the top of my list of prepared questions. After all, there has been a mystery haunting GM followers for some time now… a mystery that I’d never seen a journalist ever ask about. And there I was, sitting with one of the few people who was even capable of fully answering it. So I just waited for a pause, opened my mouth and asked:

Why do GM cars weigh more than other cars?

I had no idea what kind of answer to expect… but I definitely wasn’t expecting the answer I got.

If you’re eagerly jumping up to shout “yes” to the headline’s rhetorical question, you’d better live in Europe… or be prepared to move there. The chances of VW ever bringing its 1.4 TSI engine to the US seem dim, based on the brand’s new mass-market-oriented, big-n-cheap approach. But starting next year, Autocar reports that

VW [will be] the first manufacturer to implement the fuel-saving technology in a mass-produced TSI engine, a system that shuts off two of the four cylinders under low to medium loads, between 1400 and 4000rpm.

Volkswagen claims that the EU6-compliant unit saves 0.4 litres (0.09 gallons) of fuel per 100km, rising to 0.6 litres (0.13 gallons) per 100km when combined with VW’s stop-start system.

VW also says that the benefits become more obvious when driven smoothly and slowly: “At 50 km/h, in third or fourth gear, savings amount to nearly one litre per 100km.”

If you’re currently looking up those conversions for use in future conversations (about hypothetical engine swaps for your Em Kay Eye Vee), you’re officially a “Mr Euro” (here’s a hint: it’s cooler to use the European measures and make everyone else do the math). If you’re wondering about how reliable these engines are going to be, or what it must be like to cruise the freeway on 700 ccs of displacement you’ve probably come to the right place.

This Cadillac ad is the latest in a series of seriously good spots for the CTS-V, which started with this “Competition” ad from last Summer. But then, as I found in a short drive, the CTS-V writes its own ad copy, 556 HP at a time. And this latest spot has one minor truth-related omission: though GM rightly claims that Magneride Magnetorheological suspension was “perfected” in the CTS-V, it actually debuted in the less ad-dollar-worthy 2002 STS. And there’s no mention of the fact that the technology was developed by Delphi, then a technically independent firm, and the technology has since been sold to Beijing West Industries. Of course, these details aren’t exactly worthy of the limited time available in a 60-second spot, but it’s the truth, dammit. “Just sayin…”

Today’s announcement of a memorandum of understanding between Ford and Toyota, uniting the two firms’ pickup truck hybrid drivetrain efforts, took quite a few industry-watchers by surprise this morning. As the industry leader in hybrid technology, Toyota has limited past hybrid cooperation to licensing its drivetrain wholesale to Nissan and a patent-sharing agreement with Ford. Moreover, the last big alliance aimed at developing hybrid technology for full-sized pickups, the Two-Mode V8 hybrids developed jointly by GM, Chrysler, Mercedes and BMW, have been a huge flop on the market, with the German partners walking away from the technology after using it in only a single application each (X5/X6, and ML Hybrid). Though Toyota and Ford have worked together to prevent a messy patent war over hybrid technology, there was little to suggest that they would take the cooperation any further, let alone join forces to hybridize full-size pickups. But if you’re looking to the marketplace to explain the Ford-Toyota tie-up, you’re looking in the wrong place: this is all about the freshly-announced CAFE standard and its generous credit system.

Rattle off a list of the buzzworthy EV makers that seem likely to achieve the “holy grail of EV development,” a multi-gear electric car, and chances are that firms like Tesla, Fisker, Th!nk or even a major OEM like Nissan will make the cut. You probably wouldn’t consider the ultra-conservative British sportscar maker Morgan to be in the running, as they still build body substructures out of wood… surely the brand that’s most stuck in the early 20th Century seems an unlikely candidate for EV technical leadership. Think again…

Among the many new SKYACTIV technologies that Mazda plans on introducing to its global lineup, a unique start-stop system is one of the most important. Initially Mazda had decided not to bring its idle-stop system to the US as the EPA system didn’t measure a major improvement in efficiency, but ultimately the decision was made to make all of its vehicles idle-free by 2015. But an early test of a SKYACTIV idle-stop-equipped Mazda2 by Automotive News [sub]’s Hans Greimel reveals an interesting characteristic:

a funny thing happened when I paused for a red in Tokyo’s harbor district.

After a few moments of silence, the engine clicked on, as designed, to help keep the air conditioner going. OK, that’s normal. But as the engine jumped to life, so did the steering wheel. To my surprise, I found the engine’s start-up vibrations turning the wheel to-and-fro in my loose grip.

You know those things that you never thought you needed, but once you had them you realized you never wanted to live without them again? According to Jean-Claude Kihn, Goodyear’s senior vice president and chief technical officer, it’s time to get ready for another such technology:

“A tire that can maintain its own inflation is something drivers have wanted for many years. Goodyear has taken on this challenge and the progress we have made is very encouraging. This will become the kind of technological breakthrough that people will wonder how they ever lived without.”

Goodyear doesn’t know when its “Air Maintenance Technology” will make it to the streets, but thanks to funding from the US and Luxembourg governments, they’re making progress.

Steampunks and Atomic Age nuts rejoice! WardsAuto reports that Connecticut-based Laser Power Systems is “getting closer” to developing a prototype electric car which develops its power using the radioactive heavy metal Thorium. According to LPS’s CEO,

when thorium is heated by an external source, it becomes so dense its molecules give off considerable heat. Small blocks of thorium generate heat surges that are configured as a thorium-based laser… These create steam from water within mini-turbines, generating electricity to drive a car. A 250 MW unit weighing about 500 lbs. (227 kg) would be small and light enough to drop under the hood of a car… Because thorium is so dense, similar to uranium, it stores considerable potential energy: 1 gm of thorium equals the energy of 7,500 gallons (28,391 L) of gasoline. Prototype systems generate electricity within 30 seconds of firing a laser. This can feed power into a car, without the need for storage.

What about radioactivity? (Read More…)

A team of researchers at UC San Diego and the University of Washington, Seattle, has just published a paper titled “Comprehensive Experimental Analyses of Automotive Attack Surfaces“. Behind that dry title is a very exciting research study. In essence, they bought a modern reasonably-priced car with lots of fancy features, including a built-in cellular phone interface, and did a serious reverse-engineering exercise to determine whether it had any security vulnerabilities. It’s the most comprehensive study of its kind.

The source of today’s Quote Of The Day, a BMW M Division engineer, is clearly not a native English speaker, but he reveals just where performance cars like the new M5 are going when he says:

More and more demand is from our test engineers from the referring(?) departments and they come over and 80%, 90% are only working on the electronic systems. The other 10, 20 percent are working at the car, under the car….

Of course, the M engineers aren’t developing a car from the ground up here, but it’s still amazing that the workload is so unevenly weighted towards electronic rather than, for lack of a better term, “greasy hands” work.

When news hit late last week that one of Google’s driverless cars had been involved in a minor fender-bender, the anti-autonomous driver argument made itself. “This is precisely why we’re worried about self-driving cars,” howled Jalopnik.”Google’s self-driving car seems like the ultimate distracted driving machine.” But on the very same day, Google claimed that

One of our goals is to prevent fender-benders like this one, which occurred while a person was manually driving the car [emphasis added]

Before you know it, the other side of the debate, as epitomized by Popular Science flipped the argument, insisting that

this incident is yet another example — as if we need one — of the human capacity for error. Hopefully when cars do take over, they’ll be able to prevent these types of incidents on their own.

So yeah, there’s a pretty wide range of opinions on the issue. And with Nevada’s legalization of driverless cars, it’s only a matter of time before something happens that busts the debate wide open again. So, how do you feel about our new robot overlords? I, for one, could live with the technology for freeway/expressway use… but not without drawing some kind of clear lines around legal liability. Off-freeway? No thanks. Too few benefits from packing traffic tighter and too many other variables in traffic. What say you?

I am sitting in a parking garage in a throng of torpid auto-journalists, nearly all of whom are wearing the same glazed expression of terminal information overload. On-screen, molecules of fuel and air are doing a complicated little computer-animated dance, as narrated by Susumi Niinai, program manager at Mazda’s powertrain development division. His English, while Japanese-accented, is better than, y’know, mine, but the concepts he’s explaining approach the limit of comprehensibility to the lay-person. Mind you, it’s a pretty nice parking garage.

Some of you, like me, may have been hearing all the rumblings about Mazda’s new SKYACTIV technologies and been wondering whether it’s going to turn out to be a series of technological breakthroughs or, alternatively, a load of complete cobblers thought up by some Zoom-Zoom marketing guru.

Good news everyone! It’s the former. Bad news everyone! I have to try to explain it to you. And I borderline don’t understand it myself. Here goes…

In an extended interview with Fareed Zakaria this weekend, GM CEO Dan Akerson repudiated a lot of GM’s previous optimism about hydrogen fuel cell cars, saying

We’re looking at hydrogen fuel cells, which have no carbon emissions, zero. They’re very expensive now, but we’ve, just in the last two years, reduced the price of that technology by $100,000. The car is still too expensive and probably won’t be practical until the 2020-plus period, I don’t know. And then there’s the issue of infrastructure

The DetN points out that GM had previously said that it would have anywhere from 1,000 to “hundreds of thousands” of fuel cell cars on the road by 2010, and most recently said (in 2009) that the technology would be “commercialized” by 2015 and “cost-competitive” by 2020. So, if hydrogen is moving to the back burner, what’s moving up? Akerson revealed that

soon we’ll be introducing “bi-fuel” engines which can burn both compressed natural gas and liquid gasoline.

We’ve seen GM take early steps towards bringing a natural gas-powered car to the road, but this is the first sign from a top executive that a dual-fuel car is a certainty in GM’s near future. By talking down hugely expensive hydrogen cars and talking up cheap natural gas powerplants, Akerson sends a strong message that GM’s green car efforts are moving in a more pragmatic direction. Hit the jump for part two of the interview, in which Akerson talks gas tax and green cars.
